Directions for Use

  1. Spray Method
  • The vaccine should be dissolved in distilled water.
  • The vial of freeze-dried vaccine should be opened under water.
  • The spray apparatus should be free from sediments, corrosion and traces of disinfectants (preferably to be used for vaccination purposes only).
  • The vaccine medicated water should be spread evenly over the correct number of chickens, at a distance of 30 to 40 cm, preferably when the chickens are sitting together in dim light.
  • For 1-day-old chickens use 0,25 litre of water/1 000 birds and set nozzle to produce a course spray, falling like rain.
  • For older chickens, dissolve 1 000 doses/litre of water and set the nozzle to produce course spray (aerosol generators should be used only when this is known to be safe to chickens).


  1. Eye Drop Application
  • Dissolve the vaccine in Intervet Diluent Oculo Nasal and administer by means of a standardised dropper (usually 30 ml/1 000 doses).
  • One drop should be applied from a height of a few centimetres onto 1 eye. As an eye drop application, the drop should be allowed to spread evenly across the surface of the eye.
  • Do not release the chicken until a swallowing motion is noticed.
  • For numbers of birds between standard dosages, the next high dosage should be chosen.

Withdrawal Period
